[3] The village of Bevaix is sited in front of a small plateau, near Lake Neuchâtel, on a location showing both Bronze Age and Neolithic settlement and a priory dating to 998.

The discovery nearby of several dugout canoes and boats illuminated techniques of shipbuilding in Gallo-Roman times.

The village was predominantly agricultural until the building of a railway station in 1860, and the drainage of the surrounding wetlands around 1900, when the area became increasingly residential.

Bevaix has an area, as of 2009[update], of 10.8 square kilometers (4.2 sq mi).

[4] The municipality is located in the Boudry district, on a small, marshy plateau near Lake Neuchâtel.

The proposed merger of the municipalities of Bevaix, Boudry and Cortaillod was rejected by the residents.
